The group of valley residents and golfers who sued to restore the former San Geronimo Golf Course have been dealt a blow in court. The Trust for Public Land, which owns the property, had demurred the San Geronimo Heritage Alliance’s petition, objecting to the validity of the lawsuit. Judge Andrew Sweet sustained the demurrer last month in Marin County Superior Court, leaving the alliance with few options. “S.G.H.A. can’t add anything further,” Philip Snell, the group’s lawyer, said. “We’re out of the case.” The lawsuit alleged that the trust’s plan to turn the course into public open space violates county development code and the local community plan, and constitutes a public nuisance, turning the area into a “vacant and unsightly wasteland.” The suit also aimed to end permits for restoration work by the Salmon Protection and Watershed Network in a section of creek that runs through the former golf course. The trust objected that the alliance had not established standing to enforce the county code by proving its members suffered a special injury. The trust also contended that the code does not require a golf course to be operated on the land.  “We believe that open space, and keeping the property open to the public, is consistent with the countywide plan and the zoning,” said Erica Williams, a project manager for T.P.L. Debate over the 157-acre property has consumed local discussions around land use and open space for the last five years. Members of the alliance have been fighting the land trust and the county, with few successes, since the trust bought the course in 2017. Last March, golf advocates introduced Measure D, a ballot initiative meant to reopen the links, which failed. Alliance president Robert La Belle accused the county and T.P.L. of engaging in “corruption and deceit” over the project. He noted that supervisors Dennis Rodoni and Katie Rice donated to the “No on Measure D” effort, and that Supervisor Rodoni was a longtime member of SPAWN. That summer, Judge Sweet rejected another lawsuit filed by the alliance to stop creek restoration work planned by SPAWN. That work is slated to begin again in August.
